CUSTOM SIZE DOWN/FEATHER RECTANGLE PILLOW - Enter the dimensions and the Feather type you need. After you enter the length and width in inches of the pillow select the feather and down mix that you like. Remember the insert should be 2" bigger than the cover size so that it fills out the corners. For example a 23 x 23 cover will use a 25 x 25 insert. On the smaller sizes (less than 16" ) adding only 1" is usually enough. You may choose between a mix of poly and down and feather (this provides more bounce) or 10/90 down/feather , 30/70 down/feather, 50/50 down/feather and 100% down. The feathers have a stem the down has no stem and is just "fluff". You pay more the higher for the higher percantage of down in the pillow but you the pillow is smoother cause there are less feather stems and more "fluff".The 100% down should not have any stems and feel like all fluff.The feathers do make the pillow more solid and do offer a bit more support than just down so if the pillow is going to be used as a back support we recommend a 30/70 or 50/50 blend.Custom sizes generally require 3 to 4 days to manufacture and shipping time depends on what part of the country it is shipped to.
